The design of P-type photoswitches with thermal stability the metastable form hundreds years that would efficiently transform using excitation wavelengths above 350 nm remains a challenge in field photochromism. In this regard, we designed and synthesized an extended set 13 pyridine/quinoline hydrazones systematically investigated structure-property relationships, defining their kinetic photosw...
In this work, a series of novel Mannich's bases incorporated with Ibuprofen core and Biginelli derivatives have been reported. The synthesis process was dependent on linking hydrazone Isatin to via methylene group formaldehyde. new compounds characterized using FT-IR spectroscopy, 1H-NMR spectroscopy the physical properties.
In the title compound, [Cu2(C11H13N3O3S)2(C2H6OS)2], the Cu(II) cation is N,N',O-chelated by a deprotonated hy-droxy-imino-tosyl-hydrazone ligand and coordinated by a dimethyl sulfoxide mol-ecule. One O atom from the adjacent hy-droxy-imino-tosyl-hydrazone ligand bridges the Cu(II) cation, forming the centrosymmetric dimeric complex. The cation is in an overall distorted N2O3 square-pyramidal c...
Four acyl-hydrazones derived from 5-hydroxypicolinohydrazide and 4-hydroxybenzaldehyde (HL11), 2-fluoro-4-hydroxybenzaldehyde (HL12), 2,4-dihydroxybenzaldehyde (HL13) or 2-pyridinecarboxaldehyde (HL14) two hydrazones 2-hydrazino pyridine 4-dimethylaminobenzaldehyde (HL21) 4-diethylamino-2-hydroxybenzaldehyde (HL22) were synthesized their X-ray structures determined. Twelve rhenium(I) complexes ...
Today, the majority of drugs used in treatment diseases are obtained by synthesis. A large proportion compounds have heterocyclic structure. Therefore, synthesis new has always attracted and continues to attract scientist. It is known that bearing triazole skeleton an important place. The reactions 4-amino-triazole compounds, especially with aromatic aldehydes, been for a long time this reactio...
